Why is it important to calibrate pesticide application equipment?

Calibrating pesticide application equipment is essential primarily to prevent environmental contamination. Proper calibration ensures that the right amount of pesticide is applied to the target area, reducing the likelihood of over-application or under-application. Over-application can lead to excess chemicals running off into waterways or affecting non-target organisms, resulting in contamination of soil and water sources. Additionally, under-application may fail to effectively manage pest populations, prompting the need for further treatments that could also pose environmental risks. Therefore, calibration is a critical practice for both effective pest management and safeguarding the environment.

While the other options touch on relevant aspects of pesticide management and agricultural economics, they do not capture the primary environmental focus that calibration addresses, which is crucial for responsible pesticide use.
